Figure 64 Link Configuration Default tab Modem Mode
Unlike the T-96SR where all eight channels were programmed one channel at a time, the Guardian has a Default tab
where you can select settings that will be default selections for all eight link channels, making it easy to set all eight
channels simultaneously. (See the figure above.)
- Using the information collected from the T-96SR programming, set the RF Link information to match the system
parameters.
- Channel bandwidth is now selectable for either 25 kHz or 12.5 kHz.
- Set the Tx Power Output to the desired power level: 1-10 Watts.
- The Guardian allows for the OTA data settings to be different from the user COM port settings. Care must be taken
to ensure the OTA settings are the same as the T-96SR system settings.
o Channel bandwidth must match the existing system.
o Data rate (Baud rate) must be the same as the T-96SR.
o Data bits, Parity, and Stop bits must be the same as the T-96SR.
- The Guardian uses a slightly different yet compatible modulation scheme as the T-96SR.
o T-96SR uses DRCMSK modulation.
o Guardian uses 2 Level FSK.
Refer to the parameters collected from the T-96SR programming to set the Modem Settings. Pay close attention to the
Online Diagnostics section. If Online Diagnostics are selected in the T-96SR system, they must be enabled in the
Guardian. Whether or not the Online Diagnostics are output to the Setup port is left to the discretion of the customer.
By selecting Output Online Diagnostics Data to Setup Port, the end user can view Online Diagnostics the same as a T-
Base Diagnostic Port would show them.
